3 Claims. (01. 72-101) The invention relates to bolt anchoring devices Referring to the drawing, the numeral l desparticularly adapted for anchoring building eleignates a portion of the foundation of a buildments to concrete foundations and the like, howing and l a sleeper of the building frame disever applicable for general use for anchoring posed thereon. Heretofore various methods have various devices to a concrete structure. been used to secure the sleeper to the concrete A further object is to provide a bolt anchorfoundation, however they have been ineffective ing device comprising a sleeve or socket adapted as the sleepers are not positively anchored. To to be embedded in the concrete structure and overcome this difliculty a metallic socket 2 is having a threaded aperture therein for the reprovided, and which socket is embedded in the i ception of a bolt for holding or anchoring a wall I before the concrete sets, clearly shown in building unit to the concrete structure. Figures 1 and 2. The socket 2 is provided with A further object is to provide the outer pea threaded aperture 3 into which aperture the riphery of the sleeve with annular interrupted securing bolt 4 is threaded after it is passed ribs in spaced relation and between which the through the aperture 5 in the sleeper l The concrete is received for preventing the sleeve upper side ofthe sleeper l is preferably profrom being pulled from the concrete structure vided with a recess 6 in which the bolt head I after the concrete has set. is received on the washer 8. It will be noted that A further object is to provide the outer peafter the concrete wall sets the sleeper I can riphery of the sleeve with downwardly flared be easily and quickly attached thereto by the 2 grooves, into which grooves the concrete flows, bolts. Only one bolt is shown, however, as many and to upwardly taper a portion of the outer peas desired may be used. riphery of the sleeve thereby providing opposed The socket 2 is cylindrically shaped for subangular surfaces for additionally anchoring the stantially two thirds of its length and terminates :sleeve in the concrete. in a downwardly flared portion 9 at its lower A further object is to provide an anchoring end and is provided with spaced, annular interdevice for concrete structures comprising spaced rupted ribs l0, between which ribs the concrete sleeves embedded in the concrete and having flows for securely anchoring the socket in the bolts threaded therein and bars through which wall. It will be noted that the cylindrical porthe bolts extend into the sleeves, said bars havtion and conical porti v their peripheries n ing their ends overlapped for the reception of a at angles to each other, thereby providing adswivel connection to which may be attached ditional anchoring means for the socket. The chains or other devices to be anchored. outer periphery of the socket is provided with With the above and other objects in view the tapered grooves H, in which grooves the coninvention resides in the combination and arcrete flows, therefore it will be seen that the rangement of parts as hereinafter set forth, socket will be positively anchored against rotashown in the drawing, described and claimed, it tion within the wall when tightening or loosenbeing understood that changes in the precise ing the bolts.

embodiment of the invention may be made with- Referring to Figure 4, the anchoring means is in the scope of what is claimed without departshown in a floor l2, and the bolts 4 are shown ing from the spirit of the invention. extending through apertures of bars l3, which 40 In the drawing: bars may be angularly placed in relation to each Figure 1 is a detail perspective view of a porother if desired by passing the bolts through any tion of a concrete foundation, showing the anof the apertures i l.
